This unfamiliar territory is the borderlands of women's histories traversing the American and Canadian Wests. Specialists in women's history, settler societies, colonialism, storytelling, education, and native and borderlands studies introduced by Elizabeth Jameson and Sheila McManus pool their distinct contributions toward forging the very first comparative, transnational collection of its kind. Sixteen essays arising from the "Unsettled Pasts: Reconceiving the West through Women's History" conference at the University of Calgary comprise this foundational text. One Step Over the Line is not only the map; it is the bridgework to span the transnational, gendered divide—a must for readers who have been searching for a wide, inclusive perspective on our western past.
